Abstract

Disinfecting wipe comprising a woven or nonwoven absorbent fibrous layer impregnated with a disinfecting agent, and a layer, at least temporarily, impermeable.

Description

"Disinfectant linette"

The present invention relates to a disinfecting wipe, particularly for disinfecting toilet elements such as toilet seat, door handles, flushers, sinks and faucets.

Disinfecting and / or detergent wipes are known today which comprise an absorbent fibrous layer impregnated with a disinfecting agent or a detergent agent for sanitizing flat surfaces such as kitchen worktops, changing cousins, tables , hands,...

Unfortunately, these disinfectant wipes are not waterproof and have the result that cleaning a soiled surface is like spreading the stain on the hands of the person using the wipe. In particular, using them to clean toilet glasses, especially public toilets, often marked with traces of urine or other excrement, vomit, ... is repugnant. Indeed, the use of this type of impregnated wipes causes the urine, vomit or excrement to pass through the impregnated absorbent fibrous layer and ends on the hands of the user of the wipe.

There is therefore a need to make disinfecting wipes usable for this type of application where bacterial or viral contamination is at high risk.

Today, toilets, especially public toilets are equipped with a number of devices to make them healthier, and to reduce the spread of microorganisms, but none of these current devices can avoid sitting on glasses. dirty toilets without contaminating hands and without complex devices.

Indeed, there are soap dispensers with motion detectors to not have to touch a push button and thus transfer microorganisms from urine, vomit or excrement.

There are paper dispensers, faucets, etc. also equipped with motion detectors for the same purpose.

There are also flush toilets provided with these same motion detectors to ensure that when the user leaves the cabinet on the one hand, the bowl is rinsed and on the other hand that the pusher is not contaminated by dirt.

There are, moreover, toilets equipped with a pad impregnated with a disinfectant that protrudes when the user leaves the sanitary and which, using a rotation of the board, allows to disinfect. Unfortunately these devices are complex and expensive and do not today equip all public toilets (when they work!).

Finally, dispensers of disinfectant products are also available to be poured onto absorbent toilet paper such as towel or paper towel. Unfortunately, the supports are not very resistant to wet conditions and tear during the cleaning operation. In addition, the soils pass through and contaminate the hands of the person who cleans and in addition, the dispensers are often empty.

There is therefore a need for a long time (the unsanitary nature of most public toilets being no longer to demonstrate) to provide a simple and portable device that the consumer can afford to disinfect the toilet before use.

Although an adult finds the use of most public toilets particularly uncomfortable and uncomfortable, he will be adept enough to avoid putting his buttocks on a toilet seat when he has to use public toilets. In addition, an adult is usually better armed with immunity and conscious enough not to put his or her hands in contact with his mouth. This is of course not the case for children who are too small in size to use a toilet without sitting and who often sit in a sitting position clinging to the toilet board. In addition, a child is not necessarily aware of the risk of contamination and easily puts his hands to the mouth, eyes, nose, ... contaminating his body through the mucous membranes.

To solve this problem, the present invention provides a disinfectant wipe comprising a woven or nonwoven absorbent fibrous layer impregnated with a disinfecting agent, and a layer, at least temporarily, impermeable.

In this way, when a toilet seat surface, door handle, flush button, etc. is contaminated by dirt, the use of the disinfecting wipe focuses the dirt on the absorbent fibrous side impregnated with the agent. disinfectant, the at least temporarily waterproof layer for protecting the hands of the user by avoiding the passage of the soil of the absorbent fibrous layer to the hands of the user.

The at least temporarily impervious layer may be completely impermeable or a synthetic polymer membrane, natural or in a mixture that resists the passage of a liquid therethrough for a predetermined period of time but that past this predetermined period loses its impermeable feature to facilitate its degradation, for example to make it biodegradable and allow it to be thrown into the toilet.

Advantageously, the woven or non-woven absorbent fibrous layer is composed of cellulosic material or viscose, in particular paper, more particularly wet-resistant paper.

In a variant according to the invention, the fibrous absorbent layer woven or not is a layer of cotton fibers.

Preferably, said at least temporarily impermeable layer is a polymer layer based on polyethylene, starch polymer, rice polymer, and their mixture.

In an advantageous embodiment according to the invention, the disinfecting wipe according to the invention further comprises an intermediate layer, located between said at least temporarily impermeable layer and said absorbent fibrous layer, which intermediate layer is an absorbent material for an arranged liquid. to be impregnated.

This makes it possible to obtain disinfectant wipes with a long shelf life in which the intermediate layer may be a sponge or sphagnum which increases the amount of impregnating agent. This also avoids the drying of the wipe over time (for example in boxes already started where the contact with the air causes the evaporation of the wet phase), functioning as a reservoir.

Indeed, the use of a disinfecting wipe for cleaning a surface is performed by hand pressure which then generates the expulsion of liquid phase, which impregnates the intermediate layer, to the fibrous absorbent layer (as a buffer) since the At least temporarily impermeable layer will not allow the exit and will guide the liquid phase on the other side to be brought into contact with the soil. In addition, such an intermediate layer makes it possible to improve the absorption of the diluted soil in the disinfecting agent and to reduce the spreading.

In an advantageous embodiment according to the invention, the wipe also comprises a gripping means connected to said at least temporarily impermeable layer, in particular a lichette or strip intended for the insertion of a part of a hand of a user. This makes it possible to properly grasp the wipe and to effectively protect the hand by reducing the wiping thereof that would result in placing the hand in contact with the dirt.

In a variant of the wipe according to the invention, said at least temporarily impermeable layer comprises at least 2 thicknesses of at least temporarily impermeable material.

Therefore, one of the thicknesses of at least temporarily impermeable material is an outer layer and this outer layer may be provided with a notch for accommodating one or more fingers of a user to facilitate gripping, as a gripping means

The gripping means may also be a self-adhesive strip.

Preferably, said disinfecting agent comprises an alcoholic or biocidal phase or a detergent and optionally an aqueous phase.

Advantageously, the wipe according to the invention comprises one or more points or strips of adhesive on said at least temporarily impervious layer intended to maintain it in a folded position.

In a preferred embodiment of the invention, the disinfecting wipes are packaged in a predetermined number of 1 to 500 pouches.

Other embodiments of the wipe according to the invention are mentioned in the appended claims.

The invention also relates to a package comprising a resealable pouch and one or more wipes according to the present invention.

Other embodiments of the packaging according to the invention are mentioned in the appended claims.

The present invention also relates to a particular wall-mounted dispenser, containing a plurality of wipes according to the invention or a plurality of wipes packaging according to the invention.

Other embodiments of the wall-mount dispenser according to the invention are mentioned in the appended claims.

Finally, the present invention relates to a method of manufacturing disinfecting wipes according to the invention comprising a step of assembling an absorbent fibrous layer woven or not and a layer at least temporarily impermeable and impregnating step of said absorbent fibrous layer woven or nonwoven with a disinfectant solution.

Advantageously, said impregnation step is performed after said assembly step.

In a variant, said impregnation step is carried out before said assembly step, which depends on the assembly used and the assembly material used.

Preferably, the method according to the invention also comprises a step of insertion of an absorbent intermediate layer, between said at least temporarily impermeable layer and said woven or non-woven absorbent fibrous layer.

In addition, advantageously, the method according to the invention comprises a step of manufacturing gripping means, in particular a step of adding a lichette or strip or cutting a notch.

In one embodiment of the invention, the method also comprises a step of folding the disinfecting wipe and / or a packaging step in a pouch, case, dispenser, etc.

As can be seen in Figure 1, the wipe 1 according to the invention comprises a fibrous layer 2 absorbent woven or woven impregnated with a disinfecting agent. The fibrous layer may be composed of cellulose or viscose, in particular paper, preferably wet-resistant paper or a textile based on cotton fibers, hemp, linen, etc.

The disinfecting agent may be an antiseptic, an alcoholic phase such as denatured, camphorated, isopropyl alcohol, diluted in water, a biocide, an oxidizing agent (bleach, H2O2, etc.) or a detergent, diluted in water. These substances all have a notorious effect on microbial contaminations.

The wipe also comprises an at least temporarily impervious layer 3 which may be a polyethylene-based polymer layer; rice, starch or their mixture, preferably biodegradable.

The impermeable layer 3 may be partially folded over the fibrous layer 2 to promote retention in place by gluing, welding, sewing, ... or be a multiple layer (as in Figure 2k). In this case, the layers are fixed to the fibrous layer 2 by sewing, welding, pressing or gluing 4.

The at least temporarily impermeable layer 3 comprises in this embodiment gripping means 5 in the form of a lichette. The gripping means 5 may also be in the form of a notch (see FIG. 2B) made in the outer layer of the impermeable multiple layer 3.

FIG. 3 illustrates a particular embodiment of the invention which further comprises an absorbent intermediate layer 6 of absorbent material such as sphagnum moss, cotton, a sponge and the like to absorb soil and act as a disinfectant reservoir. .

The wipe may also have one or more points of glue 1 on the impermeable layer to maintain it in the folded position.

Such a wipe is manufactured by a method which comprises a step of assembling a woven or non-woven absorbent fibrous layer and an at least temporarily impermeable layer and a step of impregnating said woven or non-woven absorbent fibrous layer with a disinfectant solution.

Said impregnation step is performed after said assembly step or said impregnation step is performed before said assembly step.

If an intermediate layer is present, the method further comprises a step of inserting an absorbent intermediate layer between said at least temporarily impermeable layer and said woven or non-woven absorbent fibrous layer.

In addition, a step of manufacturing the gripping means (fixing a lichette or milling or cutting a notch is performed.

That there is a layer at least temporarily impermeable 3 or more, it can be folded over the edges of the fibrous layer 2 or not.

The choice of a seam, stitching, welding or gluing is indifferent to the number of layers at least temporarily impermeable.

Then, the wipe obtained can be folded accordion or following the steps of folding the ends according to Figures 4A to 4D. Once folded, the impregnated fibrous absorbent layer 2 may be visible or not to reduce its drying.

The wipe thus folded will then be packaged in individual pocket or for example in 10 wipes pouch or in packaging of 1 to 500 wipes. These packaged wipes or not can then be placed in a dispenser (for example wall 8) which comprises an outlet 9 optionally provided with a flexible wafer or membrane 10 cut to prevent the drying of the disinfectant wipe 1 and to carry out a pressure retention preventing the exit of several wipes 1 simultaneously.

it is understood that the present invention is in no way limited to the embodiments described above and that many modifications can be made without departing from the scope of the appended claims.

For example, the at least temporarily impermeable layer may be coated on one side or on both sides of a generally more rigid or absorbent cellulosic material to allow the use of more biodegradable polymers without impairing the effectiveness of resistance and non-transfer of dirt.
